First, welcome to OCC.....
It sounds like you need the following:
(1)
IH-544195-R1 LH Arm
(1)
IH-545627-R1 RH Arm
Both of these parts are NLA from Cub Cadet.
I did an internet & eBay search and found both. In addition, you could contact the sponsors at the top of the page (Cub Classics, Patton, & Houtz) to see if they have some in their inventory.
I checked with CC Specialties and they have both.
You should have NO problem finding these parts.
Finding a "print" to make you own will be impossible. You'll find "chicken teeth" before you find a print.
